supplying steam, hot Water, or the like `to the coils`13`; or heat maybe otherwise applied. rIhe pumping or elevating mechanism isthenactuated to convey the liquidand pulp from the bottom of the tank and todistribute them in a comparatively thin layer over the aerating apron35', the said aerating apron `providing a convenient means for theintro- 'duction of oxygen into the liquid, for example, into cyanid orinto ferrous sulfate solutlons.' The liquid and pulp flpw from theaerating apron back into the tank and are again brought up by means ofthe pump.

' After the charge has been agitated for a suitl able time the pumpingis `stopped and the solutions allowedto filter through the 4cells .24and to pass out through the outlet openings 27 and the valves 28. At thesame time Wash solutions, or water, are run in through the pipes 33 andunder the canvas 21. v The canvas `serves'the purpose of thoroughly andevenly distributing the-inflowing "Wash, so that there is practically nochanneling of the pulp, but an even and' thorough' displacement of theliquid therefrom.

s y terthe filtration has been operated for a suitable timejl close thevalves 28 and introduce Wash solution, or Water, through the opening 39and through the pipes 26, 31 and 525 thereby dislodging the slimes orsolid lmaterial which has collected on the filter I. then run in morewashy solution either at the Abottom of the tank,for through the cells,or introduce it at the to the best resu ts, depending on the character-of'the ore. After the charge has been agitated, heated, aerated andfiltered tothe vdesired degree, I open the valve 14 and run the contentseither to waste or subject them to such further treatment as lmay bedesired.

In this apparatus I prefer to use the filter cells described and claimedin my copending application, Serial No. 329,611, tiled August Qt 1906.ther formsof filter cells may l however be used to advantage and I donot limit myself to this term. While I have shown a square tank, Imayuse a round tank such as that shown in' my l?atents, Nos. 785,214,834.803 and 866,858.

The apparatusl will be employed for the tal'or complete recovery of theliquids f the tank, and again startl the pump an agitate` .the mixturefor a suitable time, when the and of the ore values, depending upon thecharacter of the ore. For certain ores and for certain methods oftreatment the cocoa matting and canvas covering on the bottom of thetank may be omitted.

I claim:

1. Apparatus for treating ore-pulp, coniprising a tank, means forcirculating and aerating material therein heating means for thecirculating material, a plurality of filter cells in position to besubmerged in the material in said tank,and means for withdrawing liquidfrom thetank through said cells.

2. Apparatus for. treating ore-pulp comprising a tank, means forcirculating and aerating material therein, a plurality ot filter cellsin position to be submerged in the matcrial in said tank, means forwithdrawing liquid from the tan-k through said cells, and means fordistributing wash liquid in the lower portion of said tank.

3. Apparatus for treating ore-pulp, comprising a tank, means forcirculating material therein, heating means for the circulatingmaterial, a plurality off-liter cells in position to be submerged in thematerial in said tank, and means for withdrawing liquid from the tankthrough said cells. p

4. Apparatus for treating ore-pulp, comprising a tank, filter cellsvertically disposedv therein heating means'pfor the contents of saidtank, and external connections to the upper and lower portions of saidfilter cells.

5. Apparatus fortreating ore-pulp, comprising a tank having a convergingbottom and having circulating means, filter cells in position to besubmerged in the material in saidV tank and a filter disposed above andsubstantially parallel to the bottom of said tank. t

6. Apparatus for`- treating ore-pulp, com prising a rectangular tankprov1ded with circulating means, a`v plurality of 'filter cells in saidtank in position to be submerged in the material therein,` and heatingpipes in said tank.

7. Apparatus for treating ore-pulp, comprising a rectangular tank havinga converging bottom and provided with circulating means, heating meansfor the circulating material, a plurality of filter cells in said tankin position to be submerged in the material therein, means `torwithdrawing liquid from the tank through said cells, and a dischargegate at the bottoma of said tank.

In testimony whereof I affix my signature in presence oltwo witnesses.
